I have no idea if this is the right forum as I'm new to yalls site. But I feel super noobish for needing to ask so here I am. Setting up a new salt water nano but purchased a 17.1 gallon rimless. Traditionally when I did tanks, I used HOB filters or canisters for my freshwater predators and was planning on using an ac70 with the overflow box instead of standard tube. But upon obtaining the tank, I got some serious doubts about the weight of the HOB hanging on a rimless, with skimpy silicone, tank. Iv spent so long looking and researching that I'm about to just powerhead the dang thing with no filter. Tank will be mostly zoa and gsp. Frogspawn and xenia are on the list but probably not much else. Likely no more than 1 fish for the kids.
